Abstract: 862,140. Steam superheaters. BABCOCK & WILCOX Ltd. July 29, 1959 [July 29, 1958], No. 24432/58. Class 123(3) In a water-tube steam boiler having a furnace 1 from which gases flow through a lateral pass 2 containing a secondary superheater 95 into a downpass 4 containing reheater banks 100...102 and economizer banks 45...46, a radiantly heated primary superheater 89 is disposed in the top of the furnace adjacent the inlet to the lateral pass. The superheater 89 consists of a number of vertical platens of parallel connected, single-bend U-tubes, the platens being widely spaced across the width of the furnace. The limbs of different tubes of each platen are disposed in a row, the adjacent limbs of neighbouring tubes being rigidly connected together and arranged for flow of steam therethrough in the same direction. In the form shown in Fig. 3, each platen comprises two tube groups 114, 116 each consisting of a number of tubes arranged in pairs. The tubes of the first group 114 extend from an inlet box 88 to a transfer header 115 whilst those of the second group 116 connect the transfer header to an outlet box 90. The platen group 114 comprises pairs of tubes such as the tubes 117, 118 which respectively consist of downflow. limbs 123, 126, return bends 124, 127 of small radius and upflow limbs 125, 128, the return bends being respectively angled out to the right and the left so that whilst the limbs of adjoining tube pairs alternate they all lie in the same plane. The upflow limb 128 is joined to the neighbouring upflow limb 133 of the next tube pair by a welded-on plate 141. This arrangement is repeated throughout eadh platen group so that the tubes are held rigidly in position whilst thermal stresses are avoided since the tubes joined by the plates 141 carry steam at the same temperature. In a modification, Figs. 7-9 (not shown), the superheater has a number of serially connected passes, the end tubes of adjoining passes being connected by a sliding joint. In a further modification, Fig. 11, which shows a single pass superheater, the tube limbs of adjoining pairs do not overlap. Thus, a first tube 240 has downflow and upflow limbs 241, 244 connected by a small radius return bend 243 whilst the adjoining tube 246 has downflow and upflow limbs 247, 249 connected by an oppositely directed return bend 248, the upflow limbs 244, 249 being adjacent and connected by a welded-on plate 250.

Title: Improvements in or relating to magnetic playback system and method
IPC: G11B5/335
Filed: 1956-08-15
Abstract: 799,559. Magnetic recording and reproducing apparatus. ARMOUR RESEARCH FOUNDATION OF ILLINOIS INSTITUTE OF TECHNOLOGY. Aug. 15, 1956 [Aug. 16, 1955], No. 24985/56. Class 40 (2). In a magnetic playback system a rapidly fluctuating flux is established in the core of the transducer to produce an output modulated in dependence on the recorded signal flux, the said modulated output being demodulated by detector means, and means being also provided for establishing a feedback flux of amplitude dependent upon the amplitude of the output signal. In one embodiment, Fig. 1, the core of the transducer 10 includes a reduced cross-section saturating strip 16 carrying an exciting winding 17 consisting of two parts wound in opposing directions and carrying a rapidly fluctuating current from an oscillator 19. A constant bias flux is provided by a permanent magnet 20. A pick-up winding 22 is overwound on the winding 17. In the absence of a polarizing or signal flux no net voltage is induced, but when polarizing and signal fluxes are applied an amplitude-modulated voltage proportionate to the signal flux is induced and passed via an I.F. amplifier 25, a detector and audio amplifier 26, an amplifier 27 and output device 28. Feedback is effected through a resistor 31 to the winding 22. Polarity of the magnet 20 is preferably arranged so that its flux opposes the effect of the D.C. component of the feedback current. Negative feedback results when the magnetic strength is less than the net magneto-motive force of signal and feedback apipled to the saturating strip. It is claimed that negative feedback reduces variation in signal flux in the saturating strip and allows the use of a smaller strip whereby signal to noise ratio is improved. By using sufficient negative feedback it is claimed that harmonic distortion due to non- linearity in the head is reduced to practically zero. Fig. 2 illustrates an alternative embodiment in which two saturating strips 45, 46 are employed, and polarizing current is obtained by means of a battery 55 and controlled by a rheostat 56.

A plurality of electromagnetic friction clutches are selectively engaged by the axial sliding of an annular member of magnetic material in an annular gap in the magnetic. circuits of the clutches and a common stationary electromagnet. As shown in Fig. 1, the plates 1, 2 of clutches of the type shown in Specification 629,311 are splined respectively to a common annular member 3 attached to an input shaft 5 and to individual inner annular members 6-9 connected each to one end of one of a concentric series of tubes 10-13, the other ends of which are connected by gearwheels 20-23 to different sized gear-wheels 24-27 on an output shaft 19. The member 3 comprises alternate portions 16, 17 of magnetic and non-magnetic material. An annular electromagnet of U-shaped cross-section provides an annular air gap around the member 3 in which may be moved a ring 18 of magnetic material to energize any one of the four clutches and engage the corresponding gear ratio. The winding 15 of the magnet 14 may be energized from an alternator driven from the input shaft. The energizing current may be interrupted during gear changing. A further embodiment is illustrated in Fig. 4 (not shown), in which two four-ratio gears are arranged in series to provide sixteen ratios. By positioning the ring 18 between two clutches a braking effect may be obtained.
